In which branch of American government does the president act as commander in chief and enforce laws?

The president acts as commander in chief and is responsible for enforcing laws within the Executive Branch of the American government. This role involves overseeing the armed forces and making key decisions regarding military operations, which exemplifies the president's authority in national defense. Furthermore, the Executive Branch is tasked with implementing and enforcing the laws passed by the Legislative Branch. This dual responsibility of military command and law enforcement reinforces the central role of the Executive Branch in the federal government structure. The other branches do not share these specific functions; for example, the Legislative Branch is focused on law-making, while the Judicial Branch interprets laws. Thus, the correct answer highlights the core functions and responsibilities of the Executive Branch.
